The word “locus” in genetics, much like the word “gene” has been applied to a lot of things.
For our purposes, we will use it to refer to a “chunk” of DNA that is defined by its position in the genome.
For example, around base position X on Chromosome 3:
When gametes are formed, the two copies of each locus segregate so that each gamete carries exactly one copy of each locus.
Since individuals are formed by the union of gametes, this dictates the segregation of DNA to offspring.
